[logback-dev] MDC/ThreadLocal not being cleared properely?

[Marcel Stör]

I'm wondering whether slf4j/logback (potentially) suffers from the same 
problems as log4j:

http://www.mail-archive.com/log4j-dev@logging.apache.org/msg11378.html

I'd switch from slf4j/log4j to slf4j/logback if this solved the issue.

[Abstract]
If you don't want to go through the above referenced posts...
According to Tomcat's (>=6.0.24) "memory leak detection" listener the 
log4j MDC has a memory leak: "A web application created a ThreadLocal 
with key of type (...) and a value of type (...) but failed to remove it 
when the web application was stopped." That's because log4j doesn't 
provide something like ThreadLocal#remove.

Regards,
Marcel
